By using specially designed freestanding 8 wt.% Y 2 O 3 stabilized ZrO 2 (8YSZ) specimens, a linear relationship is found between the Raman peak shift, Δω, and applied uniaxial compressive stress, σ̅ u , i.e., Δω = Π u σ̅ u with Π u being the piezo-spectroscopic coefficient. The linear relationship
